Hey guys, since the quarantine took off i started trying to improve myself, it was an ideal tike to start exercising, so i started, i wanted to do quick ones that increase my strength and endurance since i felt weaker than i felt comfortable with, i am doing sit-ups, push-ups and plank, and i feel i am ready for a new one, im torn between jumping jacks, crunches and pull-ips on a bar, what do you think, which one should i start first, and if you also have a favourite exercise, tell me additionally, stay safe c:
